An anonymous reader writes: If you have a Kindle device, you must update it before March 22 or else it's going to lose internet connectivity. Losing access to the internet means that you won't be able to use Kindle Store to purchase books, and your device won't be able to sync with the cloud. From a CNET article, "According to Amazon, the update is required to ensure the Kindle remains compliant with continuously evolving industry web standards." These are the devices that need to be updated: Kindle 1st Generation (2007), Kindle 2nd Generation (2009), Kindle DX 2nd Generation (2009), Kindle Keyboard 3rd Generation (2010), Kindle 4th Generation (2011), Kindle 5th Generation (2012), Kindle Touch 4th Generation (2011), and Kindle Paperwhite 5th Generation (2012). If you own a Kindle Paperwhite (6th or 7th Generation), or a Kindle 7th Generation, or a Kindle Voyage 7th Generation, you do not need to worry about the update. And suddenly, Amazon sending postcards to remind people about this update doesn't feel that wrong.
